Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Automating WhatsApp Web with Alright and Python

Alright is a python wrapper that helps you automate WhatsApp web using python, giving you the capability to send messages, images, video, and files to both saved and unsaved contacts without having to rescan the QR code every time.

Why Alright?

I was looking for a way to control and automate WhatsApp web with Python; I came across some very nice libraries and wrappers implementations, including:

So I tried

pywhatkit, a well crafted to be used, but its implementations require you to open a new browser tab and scan QR code every time you send a message, no matter if it’s the same person, which was a deal-breaker for using it.

I then tried

pywhatsapp,which is based onyowsupand require you to do some registration withyowsupbefore using it of which after a bit of googling, I got scared of having my number blocked. So I went for the next option.

I then went for WebWhatsapp-Wrapper. It has some good documentation and recent commits so I had hoped it is going to work. But It didn’t for me, and after having a couple of errors, I abandoned it to look for the next alternative.

PyWhatsapp by shauryauppal, which was more of a CLI tool than a wrapper, surprisingly worked. Its approach allows you to dynamically send WhatsApp messages to unsaved contacts without rescanning QR-code every time.

So what I did is refactoring the implementation of that tool to be more of a wrapper to easily allow people to run different scripts on top of it. Instead of just using it as a tool, I then thought of sharing the codebase with people who might struggle to do this as I did.

How to Master Python for Data Science

Here’s the Essential Python you Need for Data Science

you’re embarking on your journey into data science and everyone recommends that you start with learning how to code. You decided on Python and are now paralyzed by the large piles of learning resources that are at your disposal. Perhaps you are overwhelmed and owing to analysis paralysis, you are procrastinating your first steps in learning how to code in Python.

In this article, I’ll be your guide and take you on a journey of exploring the essential bare minimal knowledge that you need in order to master Python for getting started in data science. I will assume that you have no prior coding experience or that you may come from a non-technical background. However, if you are coming from a technical or computer science background and have knowledge of a prior programming language and would like to transition to Python, you can use this article as a high-level overview to get acquainted with the gist of the Python language. Either way, it is the aim of this article to navigate you through the landscape of the Python language at their intersection with data science, which will help you get started in no time.

77 Programming Language Q&A (P4)

The following article deals with questions/answers you may encounter when asked about Lexical and Syntax Analysis. Check the bottom of the page for links to the other questions and answers I’ve come up with to make you a great Computer Scientist (when it comes to Programming Languages).

324. What are the 3 approaches to implementing programming languages?

Compilation, Pure Interpretation and Hybrid Implementation

325. What is the job of the syntax analyzer?

Check the syntax of the program and create a parse tree.

326. What are the syntax analyzers based on?

Formal description of the syntax of programs, usually BNF.

327. What are some of the advantages of using BNF?

Descriptions are clear and concise.
Syntax analyzers can be generated directly from BNF.
Implementations based on BNF are easy to maintain.

328. What are the 2 distinct parts of syntax analysis and what do they do?

Lexical analysis: deals with small-scale language constructs such as name
Syntax analyzer: deals with large-scale constructs such as expressions

329. What are the 3 reasons for why lexical analysis is separated from syntax analysis?

Simplicity, Efficiency and Portability

330. What does the lexical analyzer do?

Collects input characters into groups (lexemes) and assigns an internal code (token) to each group.

331. How are lexemes recognized?

By matching the input against patterns.
